Solar-powered rainwater pump

I plan to build (or buy) a solar-powered pump to take water from our
main rainwater tank uphill to the top of the garden. This second tank
would then be able to gravity-feed a hose pipe for watering the garden,
instead of having to use watering cans (I’m lazy).

I try to mitigate climate change using computer science. I am a Research Engineer at DeepMind, mostly working on energy problems. Previously, I worked on energy disaggregation as a post-doc at Imperial College London. Read more about me…
